I believe AM commercial radio broadcasts in the USA are medium frequency, not low frequency. My AM radio tuner on my desk goes from 530 to 1700 kHz. Making good antennas for this frequency range generally requires rather physically large antennas as the wavelength is quite large, so finding objects is not really a good use of these frequencies.
